Donald Trump visit to London called off amid fears of mass protests

Source: The Guardian

Donald Trump has backed off the idea of visiting Britain next month to open the new US embassy in London amid fears of mass protests.

Government sources suggested that Washington had signalled that secretary of state Rex Tillerson would instead open the multimillion-pound embassy.
...
Officials had been examining plans for the president to meet the Queen, without the pomp of a full-blown state banquet, with the attendant risk of disruptive protests.

However, even that more modest plan now appears to have been abandoned for the time being.

('Trumpton' was a children's TV model animation over 40 years ago; someone set it up to do political satire, largely poking fun at the Tories and UKIP. And then Trump arose, and the name coincidence was too much to resist ...)

15. Well one thing he's got right. There probably will be large protests.

16. Trump will go, but not in May

They don't want him at Prince Harry's wedding, that's been made clear. If Trump went in May there would be an expectation that he'd be invited. The Brits don't want to be rude, so this is a relief to everyone.

The article linked in the OP says Trump might go next month to cut the ribbon on the new American Embassy in London.
He's still not getting a ride in the Queen's golden carriage. It's off limits to non-royalty.
